Regions:

Developing storm slabs will remain sensitive to avalanche triggering, in particular on steep slopes, throughout Saturday.

With the end of precipitation and settling, conditions will stabilize a little more for Sunday.

Snowpack Summary

With the storm snow, 25 to 40 cm of new snow cover the January 2 melt-freeze crust that supports the weight of a skier or snowboarder. The middle of the snowpack seems well consolidated, and there is a combo of laminated crusts and decomposing facets dating from December 8 at the base.

In general, the thickness of the snowpack varies from 50 to 80 cm depending on the sector and the elevation.

Weather Summary

Synopsis: The passage of a major low pressure system south of Gaspésie will leave significant amounts of snow until Saturday morning. Clearing will follow and sunshine is forecasted for Sunday.

Friday evening and night: Snow at times heavy, 10-15 cm, northeasterly winds 40 to 60 km/h, minimum -6 C, freezing level at valley bottom.

Saturday: Flurries ending in the morning then cloudy, northeasterly winds 30 to 50 km/h, maximum -6 C, freezing level at valley bottom.

Sunday: Sunny, northeasterly winds 20 to 30 km/h, maximum -6 C, freezing level at valley bottom.

Monday: Periods of snow, 5-10 cm, northeasterly winds 30 to 40 km/h, maximum -2 C, freezing level at valley bottom.

Terrain and Travel Advice

  • Be careful to keep storm day fever from luring you out into bigger terrain features.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.

Avalanche Problems

Storm Slabs

Storm slabs are developing on top of a layer of new snow that covers the January 2 melt-freeze crust. This crust constitutes an ideal sliding plane for the upper layers of the snowpack that could lead to a natural avalanches cycle.

Aspects: All aspects.

Elevations: Below Treeline.

Likelihood: Likely - Very Likely

Expected Size: 1 - 2
